Abstract: 530,305. Cements. FORSEN, L. March 2, 1939, No. 6880. Convention date, March 4, 1938. [Class 22] Portland cement, slag cement and other hydraulic binders prepared by sintering or melting processes and containing calcium silicates and aluminates are treated to retard the action of the aluminates with water and accelerate the reaction of the silicates with water by adding a retarder consisting of an alkali hydroxide and an accelerator consisting of a calcium salt more soluble than gypsum such as calcium chloride or plaster of Paris, the alkali being present in amount less than sufficient to react with the calcium salt to yield calcium hydroxide. The materials may be added to the cement or to the gauging water. The retarder may also contain lime, prepared by burning calcium carbonate at a low temperature and slaking.

Title: The manufacture of soluble aromatic sulphonamide compounds
IPC: C07C311/37
Filed: 1939-03-02
Abstract: 526,747. Sulphonamides. WINTHROP CHEMICAL CO., Inc. March 2, 1939, Nos. 6909 and 6910. Convention dates, March 5, 1938 and Aug. 6, 1938. [Class 2 (iii)] A soluble maltose-sulphonamide compound is prepared by condensing maltose with paminobenzene-sulphonamide, if desired in the presence of a trace of ammonium chloride. The reaction may be effected in methyl alcoholic solution. If relatively large quantities of ammonium chloride are present (3 per cent. or more) an insoluble compound is formed, which however can be converted into the soluble compound by treatment with dilute acid and then neutralization. Examples are given. The Specification as open to inspection under Sect. 91 also describes the preparation of the insoluble maltoside by heating the soluble maltoside in methanol solution in the presence of ammonium chloride. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 519,661.

Title: Time domain equalizers
Inventor: GOROG ETIENNE PAUL
IPC: H04L25/03
Filed: 1966-02-17
Abstract: 1,133,353. Time domain equalizer. INTERNATIONAL BUSINESS MACHINES CORP. 17 Feb., 1966 [26 Feb., 1965], No. 6934/66. Heading H4R. Time domain equalizer for correcting distortion in a data transmission system handling pulses at regularly spaced intervals comprises a tapped delay line D, Fig. 3a, to which the signal is applied and an analogue adder which receives both the input signal and the signal from the tappings of the delay lines. The amplifiers-attenuators P1 to Pm-1 are adjusted so that the first finite signal at a sampling instant in the prepulse period is fed through the amplifier-attenuator P1, after a delay equal to the sampling period, to cancel the signal level at the following sampling instant. The same signal is then fed, after a further sampling period delay, through P2 to cancel the signal in the analogue adder at the next following sampling instant, this signal being the received signal plus the signal then being fed through the amplifier - attenuator P1. Each succeeding amplifier-attenuator is thus adjusted to feed, from the delay line tap to which that amplifierattenuator is connected, an amplified or attenuated version of the first finite pre-pulse sample which will cancel, at the analogue adder, the particular input signal level then being fed to the input of the equalizer plus the proportions of the signal existing at the various tappings preceding that under consideration fed through the respective amplifier-attenuators. All the prepulse signals, except the very first signal, are cancelled in this manner. The first finite prepulse sample and the post-pulse signals, which will include additional interference added by the first part of the equalization process, are eliminated by the apparatus in Fig. 3b, in which a decision device converts the signals to binary digital form, e.g. signals over predetermined level are registered as " ONE," so that the first finite pre-pulse sample, in the absence of noise, will be registered as zero. Thereafter the threshold device feeds an output to a shift register having stages D and the outputs of the stages of the shift register are fed back via amplifier-attenuators so that the post pulse interference is cancelled in the analogue adder. The analogue adders of Fig. 3a and Fig. 3b may be combined, Fig. 4 (not shown). The system is designed for a transmission where + 1 is transmitted for " ONE " and -1 for " ZERO." The threshold device, Fig. 3b, sets the first stage of the shift register to + 1 if the input to the detector is, e.g., > +¢ and -1 if the input to the detector is, e.g., < - ¢, while if the signal lies between -¢ and +¢ the corresponding switch C1 to Cm+n - 1 in Fig. 3b is opened.

Abstract: 402,795. Gas - storage cylinders. TRIGGS, W. W., 57, Lincoln's Inn Fields, London. (Kidde & Co. Inc., W.; 140, Cedar Street, New York, U.S.A.) March 10, 1932, No. 7178. [Class 8 (ii).] A cylindrical metal container for storing gas under pressure has the walls and closed end of less thickness than that of the necked-in portion. The cylinder is made from a blank, Fig. 1, having walls of substantially uniform thickness. The thickness of the cylinder walls is then externally reduced by machining from the closed end to the open end c of the cylinder, Fig. 2. The cylinder may also be internally machined if desired. The thick end is then necked-in and finished to the required design, Fig. 4. The process is also applicable to the production of a cylinder necked-in at both ends, the primary blank in this case may be an open-ended tube.

[Also in Group XXXV] A variable, e.g. temperature or liquid level, varies impedance 10 to produce a signal applied to windings 14, 15 on two transformers 16, 17; impedances 18, 22 determine signals in windings 19, 23, one corresponding to the upper allowable limit of the variable, and the other to the low allowable limit; windings 20, 24 thus develop signals corresponding to the differences between the variable and its upper and lower allowable limits; these signals are applied to phase discriminating detectors 21, 25, one of which delivers an output when the variable moves outside its allowable limits; detectors 21, 25 control an indicator or servomotor 26 to bring the variable back between the limits defined by 18.22. Further windings 30, 31 may be used to sum the difference signals algebraically and provide at 33 an indication of the deviation of the variable from the mean of the upper and lower allowable limits.

Abstract: 568,538. Carbon black. WINGFOOT CORPORATION. May 13, 1943, No. 7646. Convention date, Dec. 24, 1942. [Class 90] The properties of impingement carbon black are modified by passing the granular or pellatized black by gravity flow through a furnace in which the material is heated in a non- oxidising atmosphere to remove adsorbed gases and then cooling the black in a non-oxidising atmosphere.

According to one modification (Fig. 2), the carbon black, charged into an upper portion 7, passes downwardly by gravity through a number of parallel pipes through a heating zone 8 and a cooling zone 9. Hot gases pass round the pipes in the heating zone and the cooling zone 9 comprises two flues 10 and 11 through which cool air and water respectively are passed. If necessary, hammering or jarring devices may be provided to prevent clogging. The product may be used as a filler in compounding rubber.
